A classic, and sometimes lesser known, yet important locality for Pyrite in Colorado is the Climax Mine. This locality is actually a SIGNIFICANT Molybdenum mine with a very large open pit and some underground tunnels. This specimen hosts a razor sharp, highly lustrous, slightly elongated, golden metallic cube of Pyrite measuring 1.0 cm on edge and is associated with a few smaller Pyrite cubes and beautiful blue-green Fluorite on "sericite" matrix. Despite the slight amount of damage, this is still a nice display specimen from this classic Colorado locality. The Climax Mine was the largest producer of Molybdenum ore in the United States, and talks of the mine reopening have been going for years, and we would hope to see more of these great Pyrites along with other noteworthy minerals from Climax to make their way back on the market.
